See the section headed "Rules with Grouped Targets" on the Texinfo page `(make)Multiple Targets`. Without this fix, Make does not know that these recipes unconditionally make *all* of their named targets regardless of which target triggers their execution, and Make will blissfully execute multiple instances of any such recipe in parallel, not only wasting CPU cycles but potentially producing incorrect results if the recipe is not atomic in its effects on the file system. With this fix, Make understands that it need only execute such a recipe once to make all of its targets. In pursuit of the above, move and combine two redundant msggen recipes into the top-level Makefile, and populate its grouped targets from the subordinate Makefiles. Changelog-None
